Question

The only thing I know how javascript uses alert (). is there any other way to help javascript debugging?

Answer 1

Using Firebug and web development tools in other browsers, you can use commands such as

console.log(myVar);

observe variables, not more destructive alert. With consoles in most development tools, you can also run arbitrary Javascript snippets without changing the actual code, which can help a lot with Javascript debugging. Oh, and the break on error function also helps.
